Why do you doubt that?

What version of gfortran are you using, and where did it come from?

For detailed information about configuring AmberTools 1.3 on OSX 10.6, go to
the "Running Amber on Mac OSX" link at

This is very likely caused by having a gfortran compiler that does not create
64-bit object files (and a gcc compiler that does do that). See the website
